Revision: 2005 July 2005 FX
Check For MAIN Switch
1. Start the engine. Then, check the following operations are car-
ried correctly.
2. Vehicle-to-vehicle distance control mode is displayed in combi- nation meter illuminates when MAIN switch is pressed “ON” for
less than 1.5 seconds and ready for operation. The illumination
goes off when MAIN switch is turned to OFF.
3. “CRUISE” illumination and ICC system display go off when the ignition switch is turned to OFF while MAIN switch is ON
(“CRUISE” illumination is ON and vehicle-to-vehicle distance
control mode is ready for operation).
Check For RESUME/ACCELERATE, SET/COAST, CANCEL Switches

LASER BEAM AIMING ADJUSTMENT
Revision: 2005 July 2005 FX
5. Pivot the edge of the target board 20° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift rates the 20 ° movement.
6. Do not place anything in the space shown in the figure (view from top). NOTE:
In case the space shown in the figure is not available, make space by covering the side of the target board
with a 400 mm (15.75 in)-size frosted black board or black cloth.
Aiming AdjustmentAKS006YM
CAUTION:

Complete all necessary work for laser beam adjustment until the adjustment completes as shown
in the procedure. If the procedure does not complete, the ICC system is inoperable.

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER on the data link connector.

CAUTION:
If “ICC” cannot be shown after several attempts, the ICC unit may have had malfunction. Repair or
replace it. Refer to GI-39, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. Self-diagnostic result appears on screen. If “NO DTC ···” is shown, check ICC warning lamp. If any mal- function is indicated, GO TO step 5.
5. According to ACS-41, "
Diagnostic Trouble Code (DTC) Chart" , perform appropriate check, and repair or
replace malfunctioning part as necessary.
6. Turn ignition switch OFF.
7. Start the engine and touch “START (NISSAN BASED VHCL)”, “ICC”, “SELF-DIAG RESULT”, and “ERASE” on CONSULT-II display in turn to erase the memory.
CAUTION:
If the memory does not erase, go to 5.
8. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC warning lamp does not illuminate.
WITHOUT CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-9, "ACTION
TEST" .
2. Stop the vehicle to start the self-diagnosis.
3. Turn ignition switch OFF.
4. From 5 seconds through 15 seconds after turning ignition switch ON, press RESUME/ACCELERATE switch 5 times, and SET/
COAST switch 5 times.
CAUTION:

Never start the engine.

Never turn the MAIN switch ON.

When operation above is not completed from 5 seconds
through 15 seconds, start again from above go to 3.

If self-diagnosis mode cannot be started after several

2. Turn ignition switch ON and start self-diagnosis.
3. During self-diagnosis mode, press CANCEL switch 5 times, and DISTANCE switch 5 times in this order. CAUTION:

Press them within 10 seconds after pressing CANCEL switch at first.

When operation is not completed within 10 seconds, start again from above go to 2.
4. DTC 55 will be shown.
CAUTION:
DTC of an existing malfunction will not be erased.
5. Turn ignition switch OFF to exit the diagnosis.
6. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC system warning lamp (Orange) does not illuminate.
